I tried this on the AFM thread, but got no takers. Here's hoping that the larger group can help me please:
I have some issues with my 3 Bank Target motor, so I ordered one from Marco. The old motor is leaking oil, so I thought that it was time to replace it. https://www.marcospecialties.com/pinball-parts/14-8023 Marco claims that this fits AFM and Jackbot.
Installing the new motor was easy as it fits perfectly in the target motor bracket. But as I took the motor out of my AFM, I found that the Shaft on the new motor was larger than the original (I think) motor that I had in my machine. The new motor will not fit the existing cam for the assembly. So, to sum it up, the original motor has a smaller shaft than the newer motor.
I just talked to Marco and they have sold 11 of these motors over the years, so they are not sure what is the issue.
